The invention discloses a stone-plastic floor with high interlayer bonding capacity, which comprises a matrix layer and a decorative layer impregnated with melamino-formaldehyde resin, the matrix layer comprises the following components in parts by weight: 80-100 parts of polyethylene resin, 8-15 parts of maleic anhydride grafted polyethylene, 4-10 parts of modified organic silicon microspheres, 300-350 parts of calcium carbonate, 4-8 parts of a calcium-zinc stabilizer, 1.5-5 parts of polyethylene wax and 1-4 parts of a lubricant. Interlayer bonding force is matched with anchoring force to form complex and diversified plate interlayer bonding forms, and layering and edge warping caused by layering are eliminated. The invention also discloses a production process for realizing industrial production. 本发明公开了一种层间结合能力高的石塑地板，包括基体层和经三聚氰胺甲醛树脂浸渍的装饰层，所述基体层成分组成包括聚乙烯树脂80-100份、马来酸酐接枝聚乙烯8-15份、改性有机硅微球4-10份、碳酸钙300-350份、钙锌稳定剂4-8份、聚乙烯蜡1.5-5份、润滑剂1-4份。通过层间粘结力配合锚固力组成复杂多样的板材层间结合形态，消除分层以及分层导致翘边现象的发生。还公开了其生产工艺来实现产业化生产。
